AbstractThe Tongue Drive System (TDS) is a non-obtrusive tongue-operated assistive device that has the potential to give persons with severe impairments effective computer access and environmental management. It detects and classifies users' voluntary tongue movements using a tiny permanent magnet recurred on the tongue and an array of magnetic sensors installed on a headset outside the mouth or an orthodontic brace inside the mouth to convert their intents into control commands. The magnetic sensors are nothing but hall-effect sensors. A transducer that changes its output voltage in response to a change in a magnetic field is known as a hall-effect sensor. In its most basic form, the sensor is an analog transducer that outputs a voltage. It is possible to calculate the distance between the hall plate and a known magnetic field. A Hall-effect sensor and a microprocessor make up the control system in the proposed tongue drive system. The data from the sensor is collected by the microcontroller. Fundamentally, this system is a wearable assistive technology in which a magnet is attached to the tongue, which sends signals to drive assistive devices based on tongue movement. Research fact says the tongue drive system provides better results with a full comfort zone as compared to other assistive technologies (Georgia Institute of Technology. (2008, June 30), “Tongue Drive System Lets Persons with Disabilities Operate Powered Wheelchairs, Computers”). Through this study, various types of assistive technologies are compared, which are available in the market. The study also illustrates the controlling of a mobile result through hall sensors and via Bluetooth connection. The results obtained as an output following command execution when the hall sensor is in an active condition and via a mobile application. Nowadays, assistive technology is used by a lot of people in various ways and it has immensely helped people who are suffering from severe disabilities as well as those around them. Thus, there is a vital need to look into it and make such systems that can improve the lives of people.
